Place ground chuck in a large mixing bowl with Worcestershire, pepper, celery seed, salt and Hellmann’s® Mayonnaise Dressing with Olive Oil and mix gently till well combined. Form 12 equal thin patties about 2 1/2 ounces each, about 6 inches across and put in the fridge. In another mixing bowl, stir together cheddar, scallions, the Hellmann’s® Mayonnaise Dressing with Olive Oil until nicely mixed.

To assemble the pocket burger, lay 6 patties on a clean workspace and divide the cheddar mixture evenly among them placing the mixture on top of each patty and right in the middle. Place 1 patty on top of each to form 6 burgers with a cheese center and carefully press the edges together to form a closed disk that kind of looks like a flying saucer. Place in the fridge until just ready to cook.

Brush each burger with a little olive oil and place on the grill, griddle or skillet and cook 7 minutes on the first side. Gently turn over and cook 6 minutes on the second side or until cooked to your liking.
